The calculation of the change in heat content is of a great importance where , the calculation of the change in heat content accompanying the burning of different fuels , helps us during designing...
The properties of solutions differ from the properties of the pure solvents forming them after dissolving a non–volatile substances at the same conditions , these new properties are called Colligative properties .
